Former senator and 2008 presidential candidate John Edwards is expected to be indicted on Friday, barring any last-minute developments, a source with knowledge of the investigation told CNN.
There have been plea discussions ongoing between Edwards' defense lawyers and federal prosecutors, but no agreement has been reached.
A grand jury has been investigating that money given to support Edwards' mistress Rielle Hunter by benefactors of Edwards should have been considered campaign donations -- a contention Edwards' team has disputed.
Edwards had not wanted to plead guilty to a felony because he could lose his law license, a source familiar with the inquiry previously told CNN.
The case involves the financial aid given to Edwards' mistress, Rielle Hunter. During their affair, Hunter became pregnant with Edwards' baby, though at first he denied he was the father.
While prosecutors believe the monetary help given to Hunter by two of Edwards' political backers should have been considered campaign donations, Edwards' attorneys disagree.
